IMPROVEIAMENT- IN Wl RE- ROPE HARNESS-TRACES.

Specification forming part of Letters Patent No. 202,153, dated April 9,1878; application filed March 20, 1878.

To all whom it may concern:

Be itknown thatl, FREDERIOKM. COLLIER, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain nev and usefulImprovements in Wire-Rope Harness-Traces, of which the following is aspecification:

The object of my invention is to provide a cheap, simple, strong anddurable trace of wire rope for harnesses, which shall be easy ofmanufacture and adapted to all the uses of the well-known leather trace,and more particu-' .larly for horse-cars and other heavy harnesses,

where strength is of the greatest importance; and it consists,primarily,in the means adapted to secure the wire rope permanently within themetal sockets provided at each end of the same, to connect with theharness and vehicle, as heretofore in devices constructed for suchpurposes, as hereinafter more fully described and set forth.

Figure 1 is a side elevation, showing my invention attached to the sidestrap. Fig. 2 is a view of a piece of wire rope, showing the method offorming the head. Fig. 3 is aview showing the same in the swivel-eye.

A represents a cable or wire rope, having at its rear end a tubularswivel-eye, consisting of the tubular piece B, which is provided with anexternal flange, E, upon its rear end, and an internal rib, F, forming abarrier to the withdrawal of the head G of the cable-wire rope A, whichis enlarged or expanded within the enlarged cavity beyond the internalrib F, as shown, being upset or headed down after it is drawn in pastthe rib F. This tubular piece B is also made internally with anincreasing bore toward its front or opposite end, which is providedexternally with an incline groove, I, around the same, leaving a slightprojecting flange, J, at its front end.

K represents an eye fitted with an internal bore, L, of a diametersufficient to receive the tubular piece B, which is placed within theeye K, with its external flanged end J forward, or so as to be pushedinto the bore L of the eye K, the tubular front portion M of which hasseveral projections, N, arranged around it, so as to permit of beingbent inward within the incline groove I, leaving their ends resting incontact with the-flange J so as to connect or hold the two parts formingthe swivel together.

The opposite or front end of the cable-wire rope A is secured within thebore of the piece P in the sameinanner as shown and described inrelation to its connection with the piece B at its opposite end, boththe end of the wire rope and the internal bore of the parts beingsubstantially prepared alike; and, the attachment bein g the same, it isnotshown ordescribed in detail. The piece 1? has at each side clips orcars, by which it may be riveted or connected to a leather strap, asheretofore, and its front end is provided with an eye, R, which receivesthe hook S, pivoted to the hames bya bolt, as usual. A guard-piece, T,is pivoted by the same bolt to the hames, and its rear end, havingahole, V, for the purpose, is passed over the curved point of the hookS, so as to give additional strength to the same. The pole-strap ordraftring W being placed on the hook, as shown, the parts are completedfor attachment to any harness designed for the purpose. The saddle andgirth-straps being attached to the improved side loop Y, provided withcross-bars and loop for breeohing-straps, as desired, the device iscomplete for use.

The cable-wire rope A is cut the desired length, being about two or twoand a half inches longer than when finished, which decrease in lengthismade in forming a head upon each end of the same after itis insertedWithin the tubular pieces. Being drawn through sufficiently, wire iswound around the same about an inch fromthe end, (more or less,) andthen the strands of the wire rope are turned or bent back uponthemselves, so as to form ahead,

as shown in Fig. 2. This is an essentialfeature in my invention, as itforms a cheap, simple, strong, and very durable connection of the wirerope to the metal end pieces.

Having thus described my invention, what I claim is- 1. In combinationwith the cable-wire rope A, having the head G, the tubular piece B,having the external flange E and internal rib F, its opposite end havingthe external groove tubular piece B, having thefiange E, groove I, andflange J, in combination with the eye K, having the tubular portion Mand projections N, all being constructed and arranged to operatesubstantially as and for the purposes set forth.

FREDERICK M. COLLIER.
